Roman Numerals

This week, we have mixed Maths with History and learned about a number system that existed long before the Arabic number system which we use today. Roman Numerals are still used today, such as on clockfaces and on the end credits of TV programmes/films so it is important that we know and can use them. They are not always as easy to use as we think they will be but Year 5 made a great start today and we will be continuing this learning later in the week.

Here are the slides and questions so that you can recap this again or learn from if you could not be at school.

      Well done Brooke. Check a, b, c and f in section 5.

      In section 7, d is correct but check the others.

      You have done well with this as it is not easy to learn a different number system. Remember that the ones number is always written in the same way (I, II, III, IV, V, VI, VII, VIII, IX) as are the tens number (X, XX, XXX, XL, LX, LXX, LXXX, XC). The tens and ones symbols can then just be put together in order to make any two-digit number.

      See if you can spot Roman Numerals on the end credits of a film. They use Roman Numerals to show the year that the film was made.

    M-500. ?
    I think M is 500 because if u notice it’s 1 5 1 5 1 5. But it goes in tens and ones and hundreds ?????????

      Good suggestion but M is 1,000. 500 is D.

      Would you now be able to write 2020 in Roman Numerals?
